Net Excess Generation Notes

For each billing period, the member’s monthly energy consumption and generation will be metered. The cumulative kWh Delivered to the member will be metered separately from the kWh Received to the grid from the member. All Delivered kWh will be charged according to the applicable rate schedule and Received energy for that billing period will be credited by an amount per kilowatt-hour at the Cooperative’s Value of Renewable Generation as determined in accordance with Exhibit A (“Excess Energy Credit”).

Excess Energy Credits that exceed the Charges for any billing period will be retained to offset Charges in future billing periods. Upon termination of this Rider or the member’s disconnection of its generating system from the Cooperative’s electrical power system (except for the Cooperative’s termination of the member’s interconnection for cause), the Cooperative shall issue a check to the member in the amount of any such retained Excess Energy Credit.

If solar credit is larger than the energy bill, the remaining credit rolls over to the next month as long as the account remains active.

As of the Effective Date of this Rider, the Cooperative’s Value of Renewable Generation is $0.065/kWh.

Compiled from public records, 2026. Tariffs and interconnection rules change; verify with Tri-County Electric Cooperative (SC) before you rely on this. The useful move: if an installer says you need a main panel upgrade, ask how these tap and interconnection policies were considered first.
